End of Day 5! ”Laser, score and level”

For this 5th day of the game jam, I implemented my levels 5 and 6, which might need some refinement.

I also refactored my code for the turrets, which now have different modes: Shoot (one direction), Shoot at player and Laser Beam.

I also added a score system, which goes up when you kill enemies, bosses and pass levels, and goes down when you get them.
